Biodiesel is a simple chemical compound that contains six or seven kinds of fatty acid esters. Biodiesel is defined as the methyl esters with carbon chain lengths between 12 and 20 of the fatty acids derived from vegetable oils for example lipid or animal fat. Vegetable oils or animal fats can be made biodiesel by transesterification reaction using alkohol.Komposisi and chemical properties of biodiesel depend on the purity, the short length, degree of saturation, and the structure of the alkyl chain fatty acid constituent.

Biodiesel is an alternative fuel from renewable sources (renewable), with the composition of fatty acid esters from vegetable oils include: palm oil, coconut oil, castor oil fence, cotton seed oil, and still there are more than 30 kinds of plants that are potential to Indonesia made biodiesel.

The process of making Biodiesel.Biodiesel is made through a chemical process called transesterification. This process produces two products of methyl esters (biodiesel) / mono-alkyl esters and glycerine which is a side product. The main raw material for biodiesel production include vegetable oils, animal fats, fat old / fat recycling. Meanwhile, as the supporting material that is alcohol. In making the catalyst needed for biodiesel esterification process. Biodiesel products depending on the vegetable oils used as raw materials and preliminary processing of these raw materials.

Alcohol is used as a reactant for the vegetable oil is methanol, but can also be used ethanol, isopropanol or butyl, but it should be noted also in the alcohol content of the water. When the high water content will affect the results of low quality biodiesel, because the content of soap, ALB and high trigiserida. Besides the results of biodiesel is also influenced by the high operating temperature of the production process, the length of mixing time or mixing speed of alcohol.

Catalyst is also required to enhance solubility during the reaction, commonly used catalyst is a strong base is NaOH or KOH or sodium metoksida. The catalyst will be chosen depending on used vegetable oil, crude oil when used with ALB content of less than 2%, well formed and also glycerin soap.

Catalysts are generally very hygroscopic and reacts to form a chemical solution that will be destroyed by the reactant alcohol. If more water is absorbed by the catalyst is a catalyst work less well so poorly biodiesel product. After the reaction is complete, the catalyst must neutralize by adding a strong mineral acid. After being washed biodiesel neutralization process can also be done with the addition of washing water, HCl can also be used for the neutralization process 318 base catalyst, when used acid to produce phosphate fertilizers phosphat (K3PO4).
